MOLD.

Specification of Letters Patent.

Patented Dec. 22, 1908.

To all whom it may concern:

Be it known that we, FRANK B. HARDING and JOHN J. BRUBEOK, citizens ofthe United States, and residents of Rockville, in the county of Parkeand State of Indiana, have invented a new and Im roved Mold, of whichthe following is a ful clear, and exact description.

The invention relates to the manufacture of concrete fence posts andlike articles, and its object is to provide a new and improved moldwhich is simple and durable in construction and readily adjusted formaking posts of diiferent sizes.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a perspective view of the improvement; Fig. 2 is an enlargedsectional plan view of one end of the mold; and Fig. 3 is a face view ofthe base end of the mold.

The sides A, A of the mold are connected with each other at one end by asectional and adjustable base end B, and the other ends of the sides A,A are connected with each other by a sectional adjustable peak end C.The sides A, A are preferably made of wood lined at their inner faceswith sheet metal, and the ends B and O are preferably made of sheetmetal, cast iron or the like.

The base end B is formed of two angular pieces B, B of which the piece Bis provided at the outside of its connecting member B with guideways Bfor the connecting member B of the other end piece B to slide in, asplainly shown inFigs. 1 and 3. The end pieces B and B have theirattaching members B and B fitted against the outer faces of the sides Aand A, and the said attaching members B, B are provided with slots Bthrough which extend clamping bolts D, D held on the sides A, A andserving to fasten the attaching members B, B in position on the sides A,A. The connecting member B of the end piece B is provided with anelongated slot B (see Fig. 3), through which extends a bolt D held onthe other connecting member B to permit of securely fastening theconnecting members B and B with each other. Now by loosening the nut ofthe bolt D the end pieces B and B allow the adjustment of thecorresponding ends of the sides A and A towards or from each other, togive the desired width to the mold at the base end thereof, and when theend pieces B and B have been adjusted then the nut of the bolt D isscrewed up, to securely fasten the end pieces B, B in place one on theother. On loosening the nuts of the bolts D, D, the end ieces B and Bmay be readily moved for isasseinbling the mold after the post is made.The length of a post is governed by the length of the sides A, A, but aslight adjustment in the length of the post gayBbe made by adjusting theend pieces The peak end C of the mold is formed of the angular membersC, C C and C of which the angular members C and C are adjustably securedby bolts E and E to the sides A and A, and the said angular members Cand C are provided with guideways C for the angular members C C to slidein,

the same as above described in reference to the members B B, so thatfurther descrip tion is not deemed necessary, it being howeverunderstood that the angular members C C are secured in place after thedesired adjustment is made on the members 0, C by bolts F, F. The outerends of the angular members C C are connected with each other by a boltF Now on loosening the nuts of the bolts F and F the members C 0 arefree to slide on the members C C, to allow of moving the forward ends ofthe sides A, A towards or from each other according to the width of thepost at the peak end. When the desired adjustment has been made the nutsof the bolts F, F are 9 screwed up to secure the members C C in positionon the members C, C The members C, C may be adjusted in the direction ofthe length of the sides A, A on loosening the nuts of the bolts E, E, tosuit the length of the posts to be made by the mold. Rods G are extendedtransversely through openings in the sides A, A to act as cores forforming holes in the post for attaching a wooden strip to the post bythe use of suitable bolts, the wooden strip being adapted to receivestaples for fastening fence wires in place on the post.

In using the mold, the latter is placed on a table or other support, inthe manner shown in Fig. 1, then the concrete material in a plasticstate is filled into the mold even with the top edges of the sides A, Aand the ends B, B, and after the concrete material has set and hardenedthe rods G are withdrawn and the remaining part of the mold is liftedofi free of the post form.

By reference to Figs. 1 and 2 it will be seen claim as new and desire tosecure by Letters Patent:

1. A mold for forming concrete posts, comprising sides, a base endformed of angular pieces, one slidable on the other and secured to thesaid mold sides, and a peak end formed of angular side pieces attachedto the said mold sides, and peak sections fastened together and slidablyengaging the said angular side pieces.

2. A mold for forming concrete posts, comprising sides, a base endformed of angular pieces, one slidable on the other and secured to thesaid mold sides, a peak end formed of angular side pieces attached tothe said mold sides, peak sections fastened together and slidablyengaging the said angular side pieces, and bolts for fastening the saidbase end arts and the said peak end parts to the said sides and one tothe other.

8. A mold for forming concrete posts, comprising sides, a base endformed of angular pieces one slidable on the other and adapted to besecured to the mold sides, a peak end formed of angular side piecesadapted to be secured to the mold sides, peak sections slidably engagingthe said angular side pieces of the peak end and adapted to be fastenedtogether, means for fastening the parts in position, and rods extendingtransversely through openings in the mold sides.

4. A mold for forming concrete posts, comprising sides, a sectional adjrstable peak end connecting the sides with each other at one end of themold, and a base end connecting the sides with each other at the otherend of the mold, the said base end consisting of two angular pieces eachhaving a side or attaching meml: er and an end or connecting member, theconnecting member of one of said angrlar pieces being provided withguideways in which the connecting member of the other piece slides, theside or attaching members of the angular pieces fitting against theouter faces of the sides of the mold and provided with slots, bolts heldon the sides of "the mold and extending through said slots,

the connecting member of one of said angular pieces having an elongatedslot, a bolt held on the connecting'member of the other piece andextending through said slot, and nuts held on the outer ends of saidbolts.

5. A mold for forming concrete posts, comprising sides, a sectionaladjustable base end for connecting the sides with each other at one end,and a peak end for connecting the sides with each other at the otherend, the said peak end consisting of angular side members engaging thesides of the mold, and provided with elongated slots, bolts held on thesides of the mold and extending through said slots, the said angularside members being provided with guideways, peak sections consisting ofangular members engaging each other at their outer portions, the innerportions of said peak sections being provided with slots and arranged toslide in said guideways in the angular side members,

bolts held on the angular side members and extending through the slotsin the peak sections, a bolt extending through the outer ends of thepeak sections, and nuts on said bolts for securing the parts together.

6. A mold for forming concrete posts, comprising sides, a base endformed of two angular pieces each having a side member and an endmember, the side members being adapted to be secured to the said moldsides and the end members being adapted to slidably engage each other, apeak end formed of angular side pieces each having one member adapted tobe secured to a mold side, and peak sections having members adapted tobe secured together and members adapted to slidably engage the othermembers of said angular side pieces of the peak end, means for securingthe parts in position, and cross bars extending through the said moldsides for forming bolt holes in the concrete post.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
